Most of us are reluctant to feed lettuce, an interesting article is extracted below which may change our mind.
豹紋龜 Leopard Tortoise

Lets explode the myth about lettuce: It is high in nitrates and is converted in the mouth into compounds that produce nitric oxide - a potent antibacterial chemical. The "disinfectant" effect of this chemical was tested and salivary production was high enough to kill even E.coli 0157 (the deadly bacterium that is so often responsible for outbreaks of food poisoning). A small trial conducted with volunteers on a trekking expedition through Nepal and Tibet showed that those who took nitrate tablets suffered less vomiting, diarrhoea and infections than the rest who did not. Contents: Protein 0.9g, Carbohydrates 2.9g, Fat 0.9g, Fiber 0.5g, Phosphorus 22mg, Calcium 20mg, Iron 0.5mg, Sodium 9mg, Potassium 175mg, Vitamin A 330iu, B1 0.06mg, B2 0.06mg, B3 o.3mg, B6 0.005mg, Folic acid 10.3mcg, Vitamin C 6mg, Vitamin E 0.5mg. So often I hear people "barring" the use of lettuce or condemning it as a "bad" food. Its not all bad, and along with a good balanced diet can actually be benificial. What is NOT recommended is a diet of lettuce alone as this will not provide all the nutrients your tortoise needs. |
